Since Eeminder works entirely through the native messaging clients (email or SMS text messaging) on your handheld device, it is device - independent and requires no installation of software to set up.

Security is commensurate with the security of the messaging channel. For email, that means you can take advantage of encryption and all of the password protection on your handheld device. Many smartphones have features that will delete all data after a certain number of failed login attempts or remotely if the device is lost.

SMS text messaging is as secure as your cellphone and it is instantaneously pushed to your cell phone. One would have to clone your phone in order to gain access to information.
